T0 all whom it may concern:

Be it known thatvl, CHARLES A. LAND- BACK, a citizen of the United States, and a resident of Perth Amboy, in the county of Middlesexand State of New Jersey, have invented a new and Improved Tile Press, of which the following is a full, clear, and exact description.

This invention relates to tile presses and has for an object to provide an improved construction wherein power may be used to perform the pressing operation without endangering the workmen or the apparatus.

Another object of the invention is to provide a power tile press wherein the power will be automatically disconnected from the pressing structure when said structure has been retracted to a given position.

A still further object is to provide a power driven tile press wherein the power is turned on manually and turned oil" automatically, the structure being such that in case the manual operating; meansis released, the automatic action will function.

In the accompanying drawings Figure 1 is a perspective view of a press disclosing one embodiment of the invention.

Figure 2 is a front view of the structure shown in l igure 1 with certain parts shown in section for better illl'istrating the corn struction.

Referring to the accompanying drawings bynumeral, 1 indicates a baseor support of any kindon which a base plate 2 is mounted, sald base plate being provided with up standing columns 3 and 1 merging together at the top for forming a horizontal section said'horizontal section being enlarged slightly larger than the threaded shaft 12 guide for this shaft whereby itniay act'as a the'sleeve 7 co-act though the threads of rotated.

shaft-for producing During the use of the device, the threads of sleeve 7 become more or less worn and,

3 A; any time.

Qhe threaded shaft 12 is rigidly secured to a power wheel 16 at the upper end while the lower end is connected in any suitable manner with the head 14: which is guided in ride-ways in bra :ets 1?. The =1. 1c is provided with an annular friction. body on the periphery which mav be leather or other material as presaid friction body 18 engaging the .iaces 19 and 20 of power disks 21 and 22 at diiierent times, dis: 21 acting as a power member to cause the shalt 12 to move downwardly while the disk acts to cause the t to move upw*'dly. Both of the dis and 22 are ri, ly secured to the power shailt which power shaft carries a pu ley 24. de, nod to receive power from any Mable source during the operation of the machine continually rotate it will be noted from Figure 2 that the shaft 23 is supported by suitable brackets 25 and 26 carried by the platform 8, bracket 25 having an openi. a; 2'? "for accommodating the lever 28. A sleeve 29 is loosely mounted on the reduced section 30 of shaft 2-3, said s eve hating; a bearing: sleeve 31 arranged in eriorly thereof and held against independent longitudinal movement by the stops and desired. friction washers 34 and may be arranged between the stops and the sleeve .29. The sleeve 29 is provided with oppositely extending: projections or pins 36 adapted to (it into the sockets 37 of the yolrc which yoke is preferably integral with the sleeve 39 and. said sleeve in turn being preferably integral. with the lever 28. By this construction and arrangement, the shaft 28 may freely rotate and by swine;- ing thelevcr 28 upwardly or downwardly cause a reciprocatoiy motion for the shaft The upper end of rod ell) is pivotally connected to the end of lever 28 op posite the sleeve 69 whereby when said rod is reciprocated the lever will be rocked. Stops all and 12 are adjustably mounted on the rod &0, said steps if desired being merely nuts threaded onto the rod and acting as stops for the respective springs 4-3 and 14, said springs in turn acting against a plate 1-5 rigidly secured to platform 8. In this way, the rod a0 and parts associated therewith are resiliently maintained in the position shown in Figure 2. The lower end of rod all is pivotally connected to a hand operated lever 46 which lever is pivotally mounted on a bracket 1-? secured to the column l.

V /hen the machine is in operation and it is desired to cause the dies 13 to move downwardly forpressing the material in mold 155, lever 46 is moved downwardly manually and spring 4A brought under tension. This movement also will act on the sleeve 29 and associated parts for shifting; the power shaft 23 longitudinally and thereby causing the disk 21 to press against the friction surface 18 of power wheel 16. ll? will be noted that the disk 21 will contact with the surface 18 near the center at first and, (onsequently, a greater power will be exerted at this time though a slower motion than. when the power wheel 16 is in a lower position. i-is the disk 21 continues to rotate and also wheel 16 continues to rotate, said wheel. will be moved. downwardly by reason of the action of the threads on the shaft 12. This downward movement will continue as long as the lever 16 is held down and until the dies 13 have threads of shaft 12 and the slipping acwhereupon the spring M will move the pa tion ofthe disk 21, the dies will rebound slightly but as the disk21 continues to ro-- into, the dies will again move down for a second compressioon thi'mgli not a blowing one. As soon this second compre sion has taken place, the operator releases the le el S, back toihe position shown in Figure 2 in doing so will cause the disk 21 to move away from operative ensagement with member 18 and disk 22 to move over into engagement therewith. This will result in the transmission of power from disk to power wheel 16 in a reverse direction and, consc q'uently, will cause the threaded shaft 12 to.

move upwardly. This upward movement automatically raised and also the power will be automatically cut oil as well as anauto-v matic throwing in of the brake 1-9, It will be noted that the springs 43 and a l act to resiliently hold the disks 21 and 22 in their operative position when permittedto do so, so that a slippine action may'occur where the resistance has reached a predetermined point.

What I claim is 1. In a tile press of the characterde scribed, a supporting frame structure, a mold adapted to be carried by said frame structure, a die. a head for carrying, said die, means for guiding said head so that the die may be forced into themold structure, a power member carried by the frame structure connected with said head, manually actuated means for setting said power mem her into operation for forcing; the die into said mold, automatically actuated means for causing said power member to be moved to an inoperative position upon releasing said manually actuated means, and'a brake" for stopping; the movement of said-power member. a

2. In a tile press of the character described, arotating power wheel, apair of driving disks, means for rotating said disks,

inanually actuated. means for moving; one disk into contact with said power wheel. automatically aetuntec means for moving the other disk into operative engagement with said power wheel, said opposite disk having a depression extending from the center outwardly a predetermined distance and. adapted to cause a disconnection of the power wheel from the disk when the power wheel has been moved to a certain positiona and a brake for stopping the rotation of said power wheel. r 2
